We aim to evaluate the associations between digital health literacy (DHL) related to COVID-19 and online information-seeking behavior among university students. Methods: A total of 3.084 students (75.7% women), with an average age of 24.2 (SD = 7.5) participated in this cross-sectional study, most of whom (36.5%) were from social sciences and pursued a bachelor’s degree (50.7%). Data on COVID-19-related DHL and online information-seeking behavior were collected using an online questionnaire. Logistic regression models were performed. Results: As the pandemic progressed, participants showed a lower chance of achieving a sufficient DHL (OR = 0.7; 95% CI = 0.6; 0.9). Using search engines more often (e.g., Google) (OR = 0.7; 95% CI = 0.5; 0.9), Wikipedia (OR = 0.7; 95% CI = 0.6; 0.9) and social media (e.g., Facebook) (OR = 0.7; 95% CI = 0.6; 0.9) decreased the likelihood of achieving sufficient DHL related to COVID-19. More frequent use of websites of public bodies (OR = 1.7; 95% CI = 1.1; 2.5) increased the odds of reporting sufficient DHL. Conclusion: DHL is associated with university students’ online information-seeking behavior in the time of COVID-19. From a community and public health perspective, programs aiming at improving DHL should be highlighted.

Purpose: Social support measures have generated empirical evidence of helping relationships and their role in family functioning and well-being. Social support networks affect parental practices and the ways in which families overcome stressful life events. Thus, it is important to gather knowledge about the different forms of support that families can benefit from. The aim of this study was to translate, adapt, and validate the Portuguese version of the Duke-UNC Functional Social Support Questionnaire (FSSQ), a three dimension measure (confidant support, affective support, and instrumental support), Method: 1058 Portuguese parents participated in the study. They were mostly married/cohabiting and employed mothers. The Portuguese version of the FSSQ contained 13 items distributed into 3 subdimensions. The data were analyzed using confirmatory factor analysis and the study of Pearson correlations. Results: The FSSQ original three-factor structure was supported by confirmatory factor analysis and the instrument showed good internal consistency. Confidant support and Instrumental support were negatively associated with Permissive parenting and Affective support was negatively associated with Authoritative parenting and Permissive parenting. All three dimensions showed low and positive correlations with Authoritarian parenting. Discussion: The Portuguese version of the FSSQ met adequate psychometric criteria and can be confidently used in family assessments of social support, whenever a brief, self-administered questionnaire would be useful for community services providers

The COVID-19 pandemic challenged parental resources pertinent to coping with lockdowns. The main objective of this work was to study parenting during the COVID-19 lockdown. Specifically at focus were parental behaviors concerning key domains for the family (daily routine, co-parenting, emotional experience, and support network) and changes related to the pandemic and associated with the parents’ employment statuses. An online survey was carried out through an ad hoc questionnaire where participants completed questions about their sociodemographic data and rated how much their family routines, their co-parenting relationship, their emotional experiences, and the support available in the family network varied on a 5-point scale. The participants included 1384 parents, of which 286 responded to open questions regarding impactful experiences during the lockdown. The results showed differences in daily routine, co-parenting, emotional experience, and support network according to the parents’ employment statuses. Between-group comparisons showed that at-home parents caring for children with governmental aids generally revealed more positive parenting behavior changes, while at-home parents who were teleworking reported more difficulties in parent-child activities and co-parenting. Furthermore, the content analysis of the data confirmed how important themes such as family dynamics, professional activities, and the relationship with the school community were throughout the participants’ accounts of gains and losses. Overall, parents’ employment statuses are associated with diverse experiences during lockdown. The COVID-19 pandemic highlighted the importance of family resources and parental resilience, particularly during circumstances jeopardizing the ever-sensitive work-family balance.

We aimed to evaluate the associations between information searching about public health and social measures (PHSM) and university students’ digital health literacy (DHL) related to the new coronavirus (SARS-CoV-2) and COVID-19. Methods: This cross-sectional study included 3,084 Portuguese university students (75.7% females), with an average age of 24.2 (SD = 7.5). Sociodemographic data, DHL questionnaire and online information concerning PHSM were gathered. Cox proportional hazards models were performed. Results: Students who searched for personal protective measures achieved in shorter time sufficient “evaluating reliability” (HR = 1.4; 95% CI = 1.1; 1.7) and “determining relevance” (HR = 1.5; 95% CI = 1.2; 1.8). Searching for surveillance and response measures was associated with sufficient “determining relevance” (HR = 1.4; 95% CI = 1.1; 1.9). Finally, those students who searched for environmental, economic and psychosocial measures achieved in shorter time “determining relevance” (HR = 1.2; 95% CI = 1.0; 1.4). Conclusions: Searching for PHSM was significantly associated with an increased likelihood of achieving sufficient DHL subscales in a shorter time. Further studies are needed, including developing strategies to increase the availability of high-quality information concerning public health and social measures and to improve (digital) health literacy.

Health literacy (HL) is a crucial factor influencing health-related decisions, including dietary patterns. The Mediterranean diet is widely recognized as one of the healthiest eating patterns. This study aims to explore the association between HL levels among adults in socially vulnerable contexts and their adoption of the Mediterranean diet. Conducted as part of a cluster-randomized trial in primary schools, the research involved 557 parents of children aged 6 to 10 who consented to participate. HL was assessed using the HLS questionnaire, while adoption of the Mediterranean diet was evaluated using the MEDAS questionnaire. Participants also provided anthropometric and sociodemographic data via a questionnaire, from which BMI was calculated (weight/height2). Education level was categorized as higher education or lower and professional status was classified based on occupational categories. Generalized linear models and logistic regression were employed for analysis. The findings indicate a direct association between HL level and adoption of the Mediterranean diet (B = 0.022, 95% CI 0.010–0.035, p < 0.001), underscoring the influence of HL on dietary choices. Specifically, the healthcare dimension of HL emerges as pivotal in shaping dietary behaviors, particularly towards the Mediterranean diet. These results underscore the importance of policies and programs aimed at enhancing HL, especially among socially vulnerable populations. Prioritizing public health interventions to improve HL is critical for promoting better dietary decision-making.
